Battery-free technology can power electronic devices using ambient radiofrequency signals

Ubiquitous wireless technologies like Wi-Fi, Bluetooth, and 5G rely on radio frequency (RF) signals to send and receive data. A new prototype of an energy harvesting module—developed by a team led by scientists from the National University of Singapore (NUS)—can now convert ambient or "waste" RF signals into direct current (DC) voltage. This can be used to power small electronic devices without the use of batteries. RF energy harvesting technologies, such as this, are essential as they reduce battery dependency, extend device lifetimes, minimize environmental impact, and enhance the feasibility of wireless sensor networks and IoT devices in remote areas where frequent battery replacement is impractical. However, RF energy harvesting technologies face challenges due to low ambient RF signal power (typically less than -20 dBm), where current rectifier technology either fails to operate or exhibits a low RF-to-DC conversion efficiency. While improving antenna efficiency and impedance matching can enhance performance, this also increases on-chip size, presenting obstacles to integration and miniaturization.

"Caramel macchiato? Did you remember the chocolate chips?"

"And- the whipped cream on top..." "And this is exactly why after I'm doing drinking this, I'm going to install a Wi-Fi module in you. You know, for something that's been offline since the days of Backstreet Boys, 'NSYNC and Britney Spears, you still catch on pretty quick! Then again, that's your my favorite floofy Motor City murderbot. Good boy!"

"-Look Rebecca, that's dessert, not coffee. I should have kept my muzzle shut about that combination years ago."

"Your point, Officer Prower?"

"Nothing, nothing at all Professor Chambers."

"I'd buy that for a dollar!"

Resident Evil x RoboCop AU where a prototype 'RoboCop 2000' or RC-2000 is developed and assigned to Raccoon City as an attempt for OCP to recover its flagging fortunes after 'RoboCop 2' and 'RoboCop: Rogue City', using a critically injured anthropomorphic fox Detroit patrolman as the basis.

Compared to the original, the RC-2000 has a full-fledged AI modeled on its template containing his full range of memories, skills, emotive profile and the like. The underlying technology is also six years newer and the signature Beretta 93R sidearm is upgraded to a .45 ACP variant. A second 93R is also included and the newer operating system contains multi-targeting capability similar to that of 'RoboCable' from RoboCop: Prime Directives.

On arrival in Raccoon City, Security Concepts placed the RC-2000's upkeep under the responsibility of RPD STARS Bravo Team medic Rebecca Chambers.

Taking over the rear security role from Rebecca, the RC-2000 ultimately was instrumental to a different outcome in Resident Evil 0 and Resident Evil 1, resulting in:

A cohesive sweep of the Ecliptic Express, Umbrella Executive Training Center and the Spencer Mansion with Bravo Team remaining together increasing survivability.

The detainment of Dr. William Birkin while en route to a meeting Wesker.

Wesker's perma-death.

The RC-2000 being damaged in a confrontation with the Tyrant, prompting Rebecca to leave Raccoon City after the raid in order to further her career, but also to make an effort to repair the robot, who she formed an attachment to.

Rebecca took over his 1992 Ford Taurus SHO patrol car as her own personal vehicle, removing the police equipment but retaining the coloration and his RPD unit callsign (308) on the side.

This was successful as of 2014 before the events of Vendetta with rumor being that she woke him up with a rather terrible piano rendition of the Moonlight Sonata.

Other Trivia:

His name is supposedly Miles Prower and his birthday is recorded as being October 16, 1980, with a record of him graduating from Wayne State University in 1996 with a criminal justice degree and a minor in physics.

He gets very flustered when she calls him a 'good boy'.

Rumor is that Miles is the one who put Rebecca on her signature caramel macchiato with chocolate chips and whipped cream.

Wireless-fidelity (“Wi-Fi”) is harmful due to radio-frequency radiation exposure, pulse-modulated RF carrying data, extremely low frequency (“ELF”) effect on the brain and the Wi-Fi memory effect in body tissues.

One of the unwanted effects of ELFs, Keith Cutter believes, is brainwave entrainment, where an external stimulus synchronises brainwaves with its frequency.

ELF refers to electromagnetic fields with frequencies between approximately 3 to 30Hz, which is the same range as our brains.  Our brains operate within a range of frequencies, with different brainwave states corresponding to specific activities:

Delta Waves (0.5-4Hz): Associated with deep sleep, relaxation, and healing.

Theta Waves (4-8Hz): Linked to meditation, daydreaming, and increased creativity.

Alpha Waves (8-12Hz): Correspond to relaxation, closed eyes and decreased cortical activity.

Beta Waves (13-30Hz): Related to attention, mental activity and cognitive processing.

Gamma Waves (30-44Hz): Involved in sensory processing, working memory and higher-order cognitive functions.

Cutter is most concerned about ELFs at 10Hz from Wi-Fi and other sources. 

In the presence of a persistent 10Hz signal, due to entrainment, the brain can shift toward that frequency. As noted above, at 10Hz the brain has decreased cortical activity.

Cortical activity refers to the electrical and chemical signals generated by neurons within the cerebral cortex, the outer layer of the brain responsible for, among other things, cognition.

E-Learning for Kids: How Virtual Classrooms Can Boost Early Education?

In a world where toddlers can operate smartphones better than most adults (and still manage to hide the remote), it’s no wonder that E-Learning is becoming the new playground for young minds. Gone are the days when kids would just smear crayons on paper. Now, they’re crafting PowerPoints, sending emojis in Zoom classes, and mastering the mute button faster than we can say “virtual classrooms.”

Book Your Free Trial Today!

https://supermathsapp.com/home/register

But seriously, how exactly is E-Learning boosting early education? And what magic are these virtual classrooms casting to keep kids engaged while keeping their socks on (mostly)? Let’s dive into this tech-savvy journey, where learning meets fun in ways you never imagined!

1. Learning in Pajamas – The Ultimate Comfort

Forget stiff uniforms and heavy backpacks—E-Learning lets kids attend school from their bedroom, kitchen, or even the couch. Learning in pajamas? Yes, please! No more chaotic mornings with missing shoes or mismatched socks (well, mostly). Imagine a world where “I forgot my homework” is replaced with “My Wi-Fi dropped!” But hey, learning should be fun, not stressful—and when kids are comfortable, they focus better!

2. Virtual Classrooms: The World’s Most Fun Video Call

Remember those endless work meetings that could’ve been emails? Well, kids are showing us how to turn video calls into something exciting! Virtual classrooms are more than just sitting in front of a screen—they’re interactive wonderlands. Teachers have leveled up, using cool tools like live quizzes, animated lessons, and digital flashcards. Who knew fractions could be more exciting than catching Pikachu?

And let’s not forget the chat box—where kids unleash their creativity with random emojis, typing “hi” to everyone, and occasionally submitting their homework in the form of a cat GIF. It’s chaotic brilliance!

3. Personalized Learning Paths (A.K.A. “Mom, Look What I Can Do!”)

Unlike the traditional one-size-fits-all approach, E-Learning offers customized learning experiences for every kid. Whether your little genius excels in math or is a budding Picasso in art, virtual classrooms adapt to their pace and interests. One minute they’re learning numbers, and the next they’re coding their first game. This flexibility not only keeps them engaged but lets their unique talents shine brighter than their favorite animated characters.

4. Play and Learn: Where Fun Meets Education

Let’s face it—kids learn best when they’re having fun. And in the world of E-Learning, fun is the name of the game! With a click, they can explore space, travel back to the dinosaurs, or solve puzzles in a magical castle. Many virtual platforms use gamified lessons, where learning becomes an adventure. Who knew that teaching the alphabet could involve racing cars, singing animals, and occasional superhero cameos? (Bonus: they might teach YOU a few things about tech!)

5. Independence with a Side of Tech Savvy

Believe it or not, E-Learning teaches kids something beyond math and reading—it’s the fine art of becoming tech wizards. Need to troubleshoot a Zoom call? Your five-year-old’s got this! Logging into a new learning app? They’re already there. Not only do virtual classrooms foster academic growth, but they also instill digital skills that are sure to make them the future IT support of your household.

Plus, with self-paced lessons, kids become little bosses of their learning schedules. Who knew your toddler would be saying, “I’ll finish that math module after snack time”?

6. No More Lost Lunchboxes or Forgotten Homework

Parents, we know the struggle of those classic school mornings: “Where’s your lunchbox? Did you finish your homework? Why are you wearing one sock?” Well, E-Learning solves at least two of those problems. Kids no longer have to pack their bags (except for snack time, of course), and assignments can’t get lost in the abyss of a messy backpack. Virtual classrooms store everything neatly in the cloud—one place where nothing mysteriously disappears!

7. Parents, Rejoice!

Let’s not forget the secret heroes in all of this—parents. E-Learning gives parents a front-row seat to their kids’ education. No more waiting for Parent-Teacher Night to figure out what’s going on. Now you can be right there as your child aces a spelling test or (more likely) discovers that the mute button is off during a particularly creative dinosaur impression. You might even pick up a few math tricks along the way!

Final Thoughts: The New Playground of Learning

In this digital age, E-Learning is more than just a trend—it’s a revolution. Virtual classrooms are opening doors to a whole new way of learning, where comfort, fun, and engagement meet. Sure, it comes with its fair share of tech glitches, awkward mute moments, and the occasional snack break mid-lesson. But in the grand scheme of things, it’s a small price to pay for the endless opportunities it brings.

So, whether your little learner is rocking their PJs, tackling numbers like a mini Einstein, or typing emojis faster than you can blink, E-Learning is here to stay—and it’s making early education more exciting than ever!

Just don’t be surprised if they start asking for “extra screen time” to finish their assignments.

Best Partner for Wireless Modules: A Comprehensive Antenna Selection Guide

n the field of wireless communication, antenna selection is crucial. It not only affects the coverage range and transmission quality of signals but also directly relates to the overall performance of the system. Among various wireless modules, finding the right antenna can maximize their potential, ensuring stable and efficient data transmission.

When designing wireless transceiver devices for RF systems, antenna design and selection are essential components. A high-quality antenna system can ensure optimal communication distances. Typically, the size of antennas of the same type is proportional to the wavelength of the RF signal; as signal strength increases, the number of required antennas also grows.

Antennae can be categorized as internal or external based on their installation location. Internal antennas are installed within the device, while external antennas are mounted outside.

In situations where space is limited or there are multiple frequency bands, antenna design becomes more complex. External antennas are usually standard products, allowing users to simply select the required frequency band without needing additional tuning, making them convenient and easy to use.

What are the main types of antennas?

External Antennas: These antennas can be classified into omnidirectional antennas and directional antennas based on the radiation pattern.

Internal Antennas: These antennas refer  to antennas that can be placed inside devices.

Omnidirectional Antennas: These antennas radiate signals uniformly in the horizontal plane, making them suitable for applications that require 360-degree coverage, such as home Wi-Fi routers and mobile devices.

Directional Antennas: These antennas have a high emission and reception strength in one or more specific directions, while the strength is minimal or zero in others. Directional antennas are primarily used to enhance signal strength and improve interference resistance.

PCB Antennas: These antennas are directly printed on the circuit board and are suitable for devices with limited space, commonly used in small wireless modules and IoT devices.

FPC Antennas: FPC antennas are flexible printed circuit antennas that are lightweight, efficient, and easy to integrate.

Concealed Antennas: Designed for aesthetic purposes, concealed antennas can be hidden within devices or disguised as other objects, making them suitable for applications where appearance is important without compromising signal quality.

Antenna Selection Guide

When selecting the appropriate antenna for a communication module, it's essential to first determine whether to use an internal or external antenna based on the module's structure.

External Antennas: These antennas offer high gain, are less affected by the environment, and can save development time, but they may take up space and impact the product's aesthetics.

Internal Antennas: These have relatively high gain and are installed within the device, maintaining a clean and appealing exterior.

 Sucker  Antennas: These provide high gain and are easy to install and secure.

Copper Rod  Sucker  Antennas: Made from large-diameter pure copper radiators, these are highly efficient with a wide bandwidth.

Rubber Rod Antennas: Offer moderate gain at a low cost.

Fiberglass Antennas: Suitable for harsh environments and ideal for long-distance signal

External Directional Antennas

Typically used in environments with long communication distances, small signal coverage areas, and high target density.

Panel Antennas have high efficiency, are compact, and easy to install, while considering the impact of gain and radiation area Yagi Antennas offer very high gain, are slightly larger, and have strong directionality, making them suitable for long-distance signal transmission; however, attention must be paid to the antenna's orientation during use

Internal Antenna Selection

Most internal antennas are affected by environmental factors and may require custom design or impedance matching

Spring Antennas are cost-effective but have low gain and narrow bandwidth, often requiring tuning for good matching when installed Ceramic Patch Antennas occupy minimal space and perform well, but have a narrow bandwidth
